Abstract: 119,999. Harcourt, C. A. April 24, 1918. Disk apparatus.-In surface-grinding machines of the kind wherein the work is reciprocated by hand, power, or otherwise in relation to a rotating grinding-tool O, the reciprocating or sliding member to which the work carrier is secured is in the form of a shaft C sliding in a sleeve B and kept from rotary motion relatively thereto by an arm D constrained at its end by a guide E. The arm passes through a slot B<1> in the sleeve and carries a friction roller D<1> working between the bars E, which are mounted on lugs E' upon the supporting framework. The work-holders J are carried upon rotatable spindles H, H<1> in brackets G, G<1> upon the shaft C, and, in order that the holders J and work E may be turned through a predetermined angle, the spindle H<1> is fitted with a wheel L in mesh with a wheel L<1> upon a spindle L<2> in the bracket G', the gear ratio of the wheels L', L corresponding to the angle between the faces to be ground on the work. The spindle L<2> is mounted in an eccentric bush M in a clamp G<2> so that the depth of engagement of the gear teeth can be adjusted. For locking the wheel L<1> in position after each complete rotation thereof, it is provided with a spring pin N to engage with a hole in the bush M. Reciprocation of the shaft C is effected from a handwheel F<2> by the engagement of a wheel F with a rack C<1> on the shaft. Clamps G<3> hold the spindles H, H<1> rigid during the grinding operation.

Title: Reinforced plastic materials
IPC: A01K87/00
Filed: 1972-05-02
Abstract: 1362531 Bonded fibre rod MORGANITE MODMOR Ltd 2 May 1972 [16 March 1971] 6931/71 Heading D1R [Also in Divisions A1 A6 and F2]  A reinforced synthetic resin rod comprises multiple wrapped layers of sheet reinforcing material and reinforcing fibres disposed between the layers, the whole being bonded together by cured resin. Organic, metallic or mineral fibres and phenolic, polyester and epoxy resins may be used. In the example a tapered rod is produced from a woven glass fibre sheet cut in the shape of a sector of an annulus and are impregnated with part cured epoxy resin. The sheet is secured to a tapered mandrel by wrapping it a few times around the mandrel and a thin coating of a liquid epoxy resin is applied. Carbon fibres are distributed on the sheet aligned parallel to the mandrel, the first third of the sheet, starting at the wider end being covered with 10cm length carbon fibres and the remainder being covered with 5cm carbon fibres of higher tensile strength but lower Youngs modulus. A pressure roller is applied to the uncoated side of the sheet whilst the mandrel is rotated to form the rod. A temporary cover of cellulose film is wrapped around the rod before it is cured in an oven. The rod is stiff at the larger diameter end and less stiff but of higher ultimate tensile strength at the other end and is used as a fishing rod. Golf clubs and vaulting poles may also be constructed. Resistance to bending may be maximised by aligning the warp or weft of the reinforcing sheet with the mandrel axis. Resistance to twisting may be maximised by cutting the reinforcing sheet on the bias and/or by laying the fibres at an angle to the mandrel.

Title: Improvements in or relating to metal cutting machines
IPC: B23B39/16
Filed: 1933-03-07
Abstract: 400,493. Revolving-cylinder pumps. TENNANT, W. J., 111, Hatton Garden, London.-(Foote-Burt Co. ; Cleveland, Ohio, U.S.A.) March 7, 1933, No. 6934. [Class 102 (i).] In a drilling or like metal cutting machine having a carriage reciprocated on the frame by fluid pressure and carrying an electric motor which drives a rotary tool thereon, a pump is also mounted on the carriage and is driven by the motor to supply fluid to the cylinder which reciprocates the carriage, the carriage only being reciprocated when the tool is being rotated. The motor drives a shaft 47 in the carriage, which rotates the drill spindles and also is connected by a chain and sprocket to the central shaft of the pump 24. A stationary axial pivot 86 is provided with axial passages 92, leading from flow-and-return pipes connected to the feeding cylinder and to radial ports 96 connected to radial cylinders 95 arranged in two series, one above the other, in a rotating cylindrical barrel 95<1>. Each pair of upper and lower pistons 97 is attached to a cross-head 98 which engages, through a ballbearing 101, with a plate 99 on a rotatable impelling ring 100 secured to the driving shaft, and mounted in ball-bearings in a casing 104. The whole pump is mounted in a casing 76 which is filled with oil. To regulate the output of the pump, and thus control the feed, the casing 104 is adjusted about a fixed pivot 105 to cause the impelling ring 100 to rotate with varying amounts of eccentricity about the axis of the pivot 86, whereby the stroke of the pistons is varied. The casing 104 is moved about the pivot 105 by links 111 attached to a hollow rod 110 carrying a piston 113 working in a fixed cylinder 114 and supplied with fluid by a pump which is driven continuously by the driving shaft which rotates the ring 100. A pilot valve 115 for the piston 113 is carried by a rod 116 slidable through the rod 110 and pivoted to a bell-crank lever 120, attached by a pin and slot to a slidable bar which is operated automatically by cams to cause the drill carriage to execute a cycle of movements. In operation, with a carriage in the retracted position, the bar is moved by a hand-operated shaft. This oscillates the casing 104 to give the ring 100 maximum eccentricity in one direction and cause the drill head to be fed rapidly towards the work. Before engaging the work, a cam adjustably secured to the frame of the machine engages a roller on the bar to move the pilot valve 115 and reduce the eccentricity of the casing 104, thereby causing the tools to be fed into the work at the cutting speed. After a predetermined travel an adjustable stop engages a spring trigger pivoted to the head and releases a hammer influenced by a spring to give a blow to the bar and thereby oscillate the casing 104 to its other extreme position and cause a rapid withdrawal of the head. When the head reaches its retracted position a cam engages the roller to move the bar to the neutral position and stop the head.

Abstract: 1422578 Film cassettes POLAROID CORP 13 Feb 1973 [17 Feb 1972] 7031/73 Heading B8M [Also in Divisions G2-G3] Photographic apparatus has a cassette receiving recess, a locking device including a shaft 130 movable in and out of the recess to engage/ disengage a cassette and a switch 139 which closes, when the shaft 130 completes its engagement of the cassette, to provide power for film transport. As shown the shaft 130 is mounted on plate 128 having a cam follower 133 touching cam 134 which is rotated through 180 degrees incrementally by motor 135. One revolution of the cam 134 moves the shaft 130 into and out of the recess once. Motor 135 is initially energized to permit the shaft 130 to engage the cassette by a switch (142), Fig. 6 (not shown), in the base of the recess. A cassette ejector 150 includes a spring plate 145 depressed by manual insertion of the cassette and held by extension 137 on follower 133. Following retraction of shaft 130 from the recess the extension 137 disengages from bar 138 and spring 146 forces the plate upwards. Each spool of the cassette is driven by an associated spindle (only 162 visible) which is retracted/advanced with the plate 128 and has a gear (e.g. 158) selectively engageable by movable belt driven gear 176. The gear 176 is moved by solenoid 178 and an opposed spring (not shown). Fig. 3 shows a film for use in the cassette which has elongated perforations 44, 45 to terminate film advance by a double pawl (not shown), apertures 39, 42 for attaching the film to the reels, and aperture 49 and aperture 46 which bump 47 used to control the film processing within the cassette. A sensing circuit (190), Fig. 6 (not shown) detects whether the film within the cassette has been processed. In combination with motion detector switches (167), Fig. 7 (not shown), on each spool spindle they control motor 135 to retract shaft 130 and eject the cassette. The motion detector switches (167) control the solenoid 178. The switch (167) on the supply reel spindle, when the circuit (190) indicates a processed film, additionally energizes motor 135 to retract the shaft 130 and eject the cassette.

Title: Improvements in or relating to remote control electric circuits
IPC: H02H7/00
Filed: 1949-03-16
Abstract: 663,235. Protective cut-out systems. ETABLISSEMENTS MERLIN & GERIN. March 16, 1949. [May 4, 1948] No. 7224/49. Addition to 649,929. Class 38 (v). The remote control circuit of the parent Specification is modified in that the contactorcontrolling relay 5 is connected across the rectifier bridge 12 without the condenser of that Specification, and the fault-detection relay 13 is latched in the operated position in which it holds the control circuit open. On closure of the button 9 an increased pulsatory current flows through the rectifier 11 and relay 5 causing the latter to be actuated and close the main contactor, the smaller current flowing through: the resistance 9<SP>1</SP> on release of the button 9 being sufficient to hold the relay 5. A current also flows through relay 13 but is inadequate to actuate it. Should a fault occur between the control wires, the rectifier 11 is by-passed and an alternating current flows through the control circuit; since, however, the alternating impedance of the relay 5 is large, the greater part of the current flows through relay 13 and the relay 5 opens, relay 13 opening the control circuit and energising an indicator lamp 14.

Abstract: 809,035. Jointing by stamping. AMP Inc. March 12, 1956 [March 15, 1955], No. 7655/56. Addition to 761,323. Class 83 (4). In a modification of the invention of the parent Specification the tool for crimping electrical connectors on to conductors including a first die and a rotatable member having a series of second dies formed around its periphery has the rotatable member supported on its side diametrically opposite to the first die by a releasable locking means which holds the rotatable member in predetermined angular positions in each of which a second die is selectively presented to the first die. The die wheel 31 is fixed to a pivot pin 28 supported in plates 18, 20 of a tool head member A pivotally mounted on a cap 10. The pin 28 is rotatable by a knurled end 30. Adjacent the dies 34 on the wheel 31 are flat portions 36 for engagements with locking means comprising rectangular members 38 and 40 (Fig. 3). The member 38 has a flange 44 at one end and an actuating button 46 at the other, the flange being provided with a foot 42. The other rectangular member 40 seats against the member 38 and is provided with a foot portion 48. Slots in each member enclose a spring 54. Pivoted spring-loaded latch means 58 engage a jaw 64 on the cap 10 to hold the tool head in position. To change the size of die the actuating button 46 is depressed against the spring 66 and thus releases the foot portion 42 from the flat portion 36 adjacent the die and permits rotation of the diewheel by the knurled end 30. Continued rotation of the die-wheel causes the edge of the wheel to come against the foot-piece 48 of the member 40, thereby moving it against the spring 54. After the segment 72 of the wheel has rotated past the foot-piece 48 the locking means again seats on one of the flat surfaces 36 to lock the wheel in position. Specification 791,720 also is referred to.

Title: Improvements in and relating to Miners' and like Safety Lamps.
Inventor: JONES THOMAS ANTHONY
IPC: F21L23/00
Filed: 1917-05-29
Abstract: 115,515. Jones, T. A. May 29, 1917. Miners' and like safety lamps comprise a combustion tube s, Fig. 1, one or more ducts e, outside the lamp glass, for carrying air from the bonnet n to a base ring g, and a dome m having a combustion aperture above the lamp burner, the arrangement being such that all the air passes beneath the dome to the flame. In a modification, Fig. 8, in which the dome is dispensed with, all the air passes to a distdibuting-chamber w in the oil vessel and thence to the exterior or interior, or both, of a central-draught burner. In the form shown in Fig. 1, air enters through apertures a and may be deflected by a ring c through the gauze d on its way to the ducts e. If the ring c is omitted, the ducts e are held in holes in the ring b and may be in contact therewith. In a modification, Fig. 4, air enters the bonnet through indentations a formed to prevent a horizontal current of air from impinging directly on the gauze d, and is then deflected by a ring c through the gauze and to the tubes e, which may be held by a ring o or in holes in the ring b. Other holes may be provided in this ring, as shown in Fig. 1, and deflector rings c, as shown in Figs. 1 and 4, may be combined in one lamp. The air traverses an annular chamber f, perforations in the wall of the oil vessel j, and gauzes h on one or both sides of a vertically-slotted detachable glass-supporting ring l flanged at its upper and lower ends. The dome m is of metal, porcelain, or other reflecting and non-conducting material. When a single air duct is used, it may be polished or plated to act as a reflector, and when multiple ducts are employed, they may be connected at their lower ends to holes in the base ring, the chamber f being dispensed with. In the form shown in Fig. 8, air passes through tubes x and a space y to the inside of the flame, and to the outside through perforations in the burner-retaining flanged ring a', or, when this is not perforated, from the interior of the bonnet through the gauze d, Fig. 1, and perforations in the flange of the combustion tube s. In further constructions, the ring l screws in the lamp base, and the oil reservoir either screws also into the base or into that ring. In testing for gas, the flame is lowered until its tip is level with the ends of the slot in the dome m.
